Car- 91 civic DX hatch,

My mods,

D16Y7 Non-VTEC
ECU - PM6
90-91 civic hatch SI 5 spd manual tranny
90-91 civic hatch SI intake manifold
Converted from to DPFI to MPFI.

Now I want to try D16Y8 VTEC, what do I need?

Can I just get D16Y8 Vtec head?
Also do I need to change my ECU again? If so, what ECU do i need?
What about the wiring? Do i need to change it also?

Please help me..

Many thanks,.

Vtec head, get a P28 or P2P and wire in vtec.
While your at it, get the Y8 intake manifold.
Get head gasket, intake manifold gasket, exhaust manifold gasket, spark plugs, plug wires, oil, coolant, head studs(bolts) if you can, y8 timing belt i think, and lots of vtec stickers =]

JRZ88DX,

So I have to get the Y8 intake manifold? The one im using right now, its from 90 - 91 civic hatch SI intake manifold I can't use it anymore???

Also is this true? I have to get the following -
tapping head, tapping block both for oil lines?

The VTEC wiring, which one? damn.. this getting me so confusing...
Man.. also I searched google- MINI-ME converted D16Y7 / D16Y8 head the pic arent there anymore.

Oh mannn I really need you guys help...

you don't have to get the y8 manifold, just a suggestion, it has better flow. For vtec you have to wire up the solenoid and pressure switch to the ecu and the switch also needs to be grounded. i don't think you need to tap any oil lines.

according to

you just need to do some intake manifold wiring along with vtec. I just did a b7/z6 mini me while converting my CRX to mpfi and obd1. Just be patient. Don't rush, make sure your cutting correct wires and torquing down correctly

Man bro. JRZ88DX,

I did lot of research now deeper I've read it.. the more confuse I get....

Hey right now im using '90-'91 civic hatch SI intake manifold with D16Y7 head.Now If i get the D16Y8 head can i still use the same manifold? or gotta change it?



Also the ECU man... P28, P2P, PEPE lol.... so much headache, my head feel like twisted inside..which one will best for EF setup with D16Y7 bottom? btw, I did the DPFI to MPFI harness conversion.

Many thanks.

He already answered your question regarding the manifold, you can reuse your 90-91 Si manifold.

Regarding the ECU, really what you have to decide is whether you want to run OBD1 or OBD2. Honestly, I think you're making it more complicated for yourself than it really is. Basically if you look in the FAQ and use GOOGLE you'll see all the pictures you need. JRZ88DX already answered your question in the first response.

You do not have to tap anything for VTEC. As for wiring, you don't have VTEC so you have to ADD it in. There's nothing confusing about it, you don't have it so you have to add it.

Make it simple in your mind, you are replacing one head with another, the new one just happens to have VTEC so you have add the wiring and run an appropriate ECU of your choice.
